The synergistic incorporation of Pb2+ and Cu2+ enhances visible-light absorption, promotes charge-carrier separation, and improves the structural robustness of ZnO, yielding an efficient and reusable photocatalyst. These PbCuZnO nanocomposites therefore show strong potential for practical wastewater treatment and environmental clean-up applications.
